# No standards

MK43 and JM53 do not list a M1III standard (but M0III and M2III
standards). Landi Dessy & Keenan (1966) do not list standards between
M0III and M1.5III. GrayCorbally10 do not list a M1III standard.

    Keenan quoted three different classifications for this star. Adopt

   Not a strong pedigree as a standard. Adopt "M1III" from Keenan63. 

ups Vir = HR 5366 = HD 125454 (V=5.2)
    M1IIIab: Keenan76(via Garcia89)

    Need to double check this. Hopefully "ups" was not confused as "nu".
